Escherichia coli (E. coli) and Salmonella enterica (SE) infections in pigs are major source associated with enteric disease such as post weaning diarrhea. The aim of this study was to investigate the effects of Pediococcus pentosaceus in weaned piglets challenged with pathogen bacteria. In Experiment.1 90 weaned piglets with initial body weights of 8.53 ± 0.34 kg were assigned to 15 treatments for 2 weeks. The experiments were conducted two trials in a 2 × 5 factorial arrangement of treatments consisting of two levels of challenge (challenge and non-challenge) with E. coli and SE, respectively and five levels of probiotics (Control, Lactobacillus plantarum [LA], Pediococcus pentosaceus SMFM2016-WK1 [38W], Pediococcus acidilactici K [PK], Lactobacillus reuteri PF30 [PF30]). In Experiment.2 a total of 30 weaned pigs (initial body weight of 9.84 ± 0.85 kg) were used in 4 weeks experiment. Pigs were allocated to 5 groups in a randomized complete way with 2 pens per group and 3 pigs per pen. Supplementation of LA and 38W improved (p < 0.05) growth performance, intestinal pathogen bacteria count, fecal noxious odor and diarrhea incidence. In conclusion, supplementation of 38W strains isolated from white kimchi can act as probiotics by inhibiting E. coli and SE.

This study was aimed to propose the basic information for the establishing the urban landscape plan of Kyoungju, which is one of the most famous history city of Korea. The study proceeded with three stage. The first and the second stage were to urban landscape. The third stage was practically to evaluate the urban landscape of Kyongju with case study. The evaluation element of urban landscape were categorized with four divisions whits is architectural features, streets facilities, natural features, and historic features, and all were composed with 22 elements. The degree of Importance and Satisfaction on the evaluation had been done urban Importance-Performance analysis method. The result study were as follows, the first, the citizens of Kyongju had more interests on improving the man-made landscape elements of buildings, streets facilities, etc. than historical landscape elements of mountains, rivers, parks, etc. The second, the improvement of the man-made landscape elements should be focused on building forms and materials rather than colors and heights of it. It was, above all, revealed that the harmonization between building forms and surrounding natural landscape and conservation of traditional features of it were the most important thing. The design of traffic facilities and large scale of road advertisement board were also considered something important to improve the urban landscape of Kyongju. The third, It was also revealed that the improvement of visual and physical approach to river ran through the city was the important thing to change the people's landscape cognition on natural environment. The fourth. The non-physical elements of urban landscape such as a activity density and behavior pattern should also be handled with same as physical landscape elements. All of these research result above mentioned reached the conclusions that the Kyoungju city government needed to convert the cognition of urban landscape. That is, improving the urban landscape of Kyoungju is not the luxurious one, but the most valuable and urgent thing in context of enhancing the quality of life of peoples and the city identification of Kyoungju. Finally, This research proposed that the city government have to establish the urban landscape design plan, approach to the physical form of urban environment with landscape design mind, and operate the landscape deliberation system with creation of new regulation.

Spring, groundwater and thermal water from the area and the vicinity of Mt. Geumjeong and Mt. Baekyang, Pusan city, has been sampled and analyzed for major and minor elements. According to the Piper diagram, spring water belongs to Ca^2^+-HCO_3^- and Na^+-HCO_3^- types, groundwater to Ca^2^+-HCO_3^- type, and thermal water to Na^+-CI^- type. Based on the phase stability diagrams of [Ca^2^+I/[H^+]^2, [Mg^2^^+I/[H^+]^2, and [Na^+I/[H^+] vs. [H_4SiO_4], spring water, groundwater and thermal water are mostly in equilibrium with kaolinite. The result of factor analysis shows three factors (factor 1,2 and factor 3) for the spring water, the groundwater and the thermal water which are represented by the influence of the dissolution of feldspar, calcite, anthropogenic sources (domestic and industrial wastes) and salt water.

평가적 이미지와 태도모형 : 새로운 태도모형 개발을 중심으로 With special reference to developing the new attitude model

조세환 경주대학교 1996 論文集 Vol.8 No.-

This study as a means to study the evaluative image of city, proposed the new attitude model(A) which is a function of value(v) and satisfaction(s), criticizing the existing model, A=f(s) with review of perception and image theory. Evaluative Image is one kinds of the approach in studying the image of city, and concerns for the relationships between knowing what elements of city environment are more important and predicting what kinds of behavior would be happened. For the testifying the new attitude model, A=f(v,s), it was applied to the Kyongju which is historic, culturaland tourist-oriented city, due to having variety of city environmental elements. As a results of the case study, the following were found. 1. It was revealed that value was one of the important concept in image study, and also was having different level as other studies have shown. But, the existing theory of evaluation of satisfaction could not find the value concepts in it self, missing the critical method of decision making as a response to the evaluation, especially in case of having the same level of satisfaction. 2. The comparison between Attitude Model and Satisfaction made it clarified that Attitude Model was more useful one to effectively evaluate the environment, because of reflecting the value concepts properly and having the reliability. 3. Especially, the relationship between level of value and satisfaction didn't show the regular one, this accentuates the necessity of two variables of value and satisfaction simultaneously in analyzing evaluative image. 4. Above finings verified the validity and identity of the new Attitude Model proposed in this study to the existing attitude model which deal with only a variable of satisfaction. This findings conclude that the new attitude model suggest better alternative to effectively evaluate the qualityof the city environment, and especially to determine on which environmental element the political focuses should be due to knowing of its values and accomplishments. But, further research is required to fing the relationship between the results of the evaluation and the behavior.

목적: 장관골 감염성 불유합의 치료 시 항생제 혼합 시멘트 정을 이용한 이단계 재건술의 결과를 분석하고자 한다. 대상 및 방법: 1998년 1월부터 2002년 9월까지 장관골 감염성 불유합으로 이단계 재건 수술을 받은 41예 (대퇴골 26예, 경골 15예)를 대상으로 하였다. 일단계 수술에서는 광범위한 변연 절제술, 부골 제거 및 세척술과 기존 고정 장치의 제거 또는 외고정 장치로의 교환을 시행한 후 시공 (dead space)과 불유합 주변 연부조직 내 항생제 혼합 시멘트 정을 삽입하였다. 임상적 감염 증상이 호전된 평균 8.7주 (3주~32주) 후 이단계 재건술로서 Ⅰ군은 내고정 장치 (금속판 5예, 골수강내 금속정 8예), Ⅱ군은 외고정 장치 (Ilizarov 25예, Monofixator 3예)로 각각 고정하고 17예에서는 골내 이동술이나 골 연장술을 시행하였다. 양군 모두 필요한 경우 골 이식과 시멘트 정의 교환을 추가하였다. 추시 기간은 16개월에서 최장 71개월로 평균 45개월 이었다. 치료 결과는 골유합 기간 및 Paley 방법에 의한 방사선상 골유합 상태와 하지 기능으로 평가하였다. 결과: Ⅰ군 13예 전부와 Ⅱ군 28예 중 26예에서 감염의 치료와 골유합을 얻었다. 이단계 재건술 후 골 이식술, 골 소파술, 외고정 핀 교환과 각변형 교정술, 피부 이식 또는 근육 피판 회전술 등의 보조적 시술이 Ⅰ군은 평균 2회, Ⅱ군은 평균 6.2회 추가되었다. 평균 골유합 기간은 Ⅰ군이 19.3주이고 Ⅱ군이 23.1주로 내고정군이 더 빨랐다. 방사선상 Paley 골유합 상태는 Ⅰ군이 우수 8예, 양호 5예이었고, Ⅱ군이 우수 18예, 양호 7예, 보통 1예, 불량 2예 이었다 (p=0.492). 기능적 결과는 Ⅰ군에서 우수 6예, 양호 6예, 보통 1예 이었고, Ⅱ군에서는 우수 10예, 양호 13예, 보통 3예, 불량 2예 이었다 (p=0.267). 결론: 항생제 혼합 시멘트 정의 골수염 치료 효과가 관찰되었으며, 감염이 호전된 후 내고정 장치로 교환해 준 군이 외고정을 유지한 군에 비하여 추가 수술 횟수가 적고, 골유합 기간도 빨랐다. Purpose: To evaluate treatment results between internal na external fixation groups in two-stage reconstruction of infected nonunion of long bones using antibiotics-impregnated cement beads. Materials and Methods: In the first stage, preexisting hardwares were removed and radical debridement was done. The dead space was filled with antibiotics -impregnated cement beads and the nonunion sits was immobilized by external fixation, cast or skeletal traction. In the second stage, all cases were divided into two groups; the nonunion was fixed by internal fixation in group Ⅰ versus external fixation in group Ⅱ. The intervening period between the first and second stage was average 8.7 weeks (range, 3~23 weeks). Results: The follow-up period was average 45 months (range, 16~71 months). Infection control and bone union were achieved in all 13 cases of group Ⅰ. Infection recurred in two of 28 cases in group Ⅱ, one underwent above-knee amputation and the other case was lost in follow-up. The mean number of supportive operations including repeated curettage, augmentation and change of infected pins, angular correction, and soft tissue flap was average 2 and 6.2 times respectively in group Ⅰ and group Ⅱ. Bony union period was average 19.3 and 23.1 weeks in each group. According to Paley's classification, group Ⅰ was similar to group Ⅱ in bony and functional result (p>0.05). Conclusion: Antibiotics-impregnated cement beads provided positive effect on infection control. Internal fixation group showed less number of additional operations and earlier bony union than external fixation group.

Internal derangememt of TMJ is defined as an abnormal relationship of articular disk to the Mandibular condyle, fossa and articular eminence. Anterior disk displacement of the disk causes the common symptoms of reciprocal clicking and limitation of mouth opening. Most Patients with internal derangements can be managed by conservative teatments. But surgical treatment is indicated for those patients who have chronic internal derangement that has failed to respond to nonsurgical treatment. The objective of surgical treatment is to eliminate pain and to restore normal function. Meniscectomy is indicated for the internal derangement of disk with perforation and gross morphological changes, nonreactive to conservative treatments. After meniscectomy, variable materials have been used for disk reconstruction. We present a case of interanal derangement of TMJ that was sucessfully treated by meniscetomy and autogenous auricular cartilage graft for disk replacement.

함세영,김문수,성익환,이병대,조병욱,김광성,김성이 부산대학교 환경문제연구소 2000 環境硏究報 Vol.18 No.-

This study is aimed for estimating hydraulic parameters using the Cooper-Bredhoeft-Papadopulos, the Hvorslev, the Bouwer & Rice analyses of data obtained by the slug test, and for characterizing hydraulic properties at the test holes in relation to drill core data. The study area was divided into four subareas far which the hydraulic characteristics was considered. The relationship among hydraulic parameters obtained by the three slug test analyses was also considered. The difference of hydraulic conductivity estimates between the injection slug test and the withdrawal slug test seems to be caused by the permeable fracture distribution around the test hole and the disturbance of fine materials in the fractures induced by the pressure variation due to slug injection and withdrawal. The hydraulic conductivity estimates calculated by the Cooper-Bredhoeft-Papadopulos, the Hvorslev and the Bouwer & Rice analyses range from 10-8 to 10-5m/sec, and the average ranges from 10-7 to 10-6m/sec.
